To prevent accidental modifications to these settings you can enable a 4-digit installer code. This code is pre-programmed to 3262 and can be enabled in the Thresholds option menu. Installation Wizard The Installation Wizard takes you step-by-step through a series of choices regarding the HVAC equipment intended to be connected to the Equipment Interface. Simply answer the questions accordingly and press Next to advance to the next screen. Once completed you will be shown a diagram of the wiring connections that reflects the choices made during the wizard process. You can press Back to go back and make any changes. Once you are satisfied with the setup, press Done. Equipment The equipment setting will allow you to manually configure the various devices that are connected to the Equipment Interface. Heat Pump This section allows you to enable and configure up to a 2 stage heat pump. If a second stage is required you must configure an Accessory relay to control that stage Geothermal/Ground Source Heat pump If you select Yes, this tells the system a geothermal or ground source heat pump is being controlled. This helps the Thermostat determine optimum performance and default settings. If you select NO, the system will optimize for an air-to-air heat pump. O/B Energize on Cool If you choose Yes, the reversing valve output (O/B terminal) will activate when there is a call for cooling. If you select No, the relay will energize when there is call for heat Min Cycle Off Time Enables you to configure the compressor off time between cycles. This is adjustable from 240 - 900 Seconds. Min Outdoor Temp Allows you to set the minimum outside air temperature at which the compressor will be disabled. This performs two functions: You can set it to prevent the compressor from going on when the outdoor temperature is too low, thus resulting in damage to the compressor. You can also set this value to determine when you want the auxiliary heat (if installed) to engage to help meet the set temperature. The temperature range is adjustable from 0°F (-17.8°C) - 65°F (18.3°C) or can be completely disabled. You will need an internet connection for this feature to operate properly. Allow Heat Pump/Auxiliary Heat to Run Simultaneously If you select Yes and there is a source of auxiliary heat, it will turn on in addition to the heat pump. The heat pump will be energized for the first 30 minutes. If, after 30 minutes, the set point has not been met, the auxiliary heat will be energized to assist the heat pump in meeting the load.If you select no, the heat pump will be energized for up to 2 hours.

This option should also be used for installation where the heat pump evaporator coil is downstream from the source of auxiliary heat. Furnace (Auxiliary Heat) Allows you to enable and configure up to a 3-stage conventional heat source. If you have selected Heat pump as your primary source, this feature will allow you to configure the auxiliary heat connected to the system. Furnace Type Allows you to configure the type of furnace connected. This allows the Smart Thermostat to optimize its algorithms based on the type of fuel and typical characteristics of the chosen system. Choose the option that best represents the type of heating system installed. Heat Stages Allows you to configure up to 3 stages of heat. If you require a third stage, you must configure an accessory relay to control that stage. Heat Fan Control This option allows you to determine if the system fan is controlled by the system during heat cycles, or if the Thermostat is required to control the fan. Normally the HVAC system controls the fan during heat cycles. Air Conditioner Allows you to enable and configure up to 2 stages of air conditioning. If you require a second stage, you must configure an accessory relay to control that stage. Staging Method of Operation The ecobee Smart Thermostat uses a unique method for staging for multi-stage heating or cooling. It uses a combination of intelligent algorithms and past performance to determine when to activate the stages. When there is a call for heat or cool, the system computes how long it would take for the system to reach the desired set point in stage 1, stage 2 or stage 3 accordingly. It will determine the highest stage at which a minimum of 10 minutes of run time is required. It will then automatically start the system at that stage (ie if it calculates that it will take 15 minutes at stage 2 but only 7 minutes at stage 3, the system will immediately turn on stage 2 to meet the set point). If the calculation indicates to start at stage 1, and it takes more than 10 minutes to reach the set point, it will automatically engage stage 2. If stage 2 runs for more than 10 minute without reaching the set point it will activate stage 3. A minimum run time of 10 minutes is used to ensure that proper circulation throughout the system and that minimum cycle times are maintained. For heat pumps with auxiliary heat, the operation of the auxiliary heat will depend on the configuration of the Allow Heat Pump/Auxiliary Heat to Run Simultaneously. Accessory relays Accessory relays are generic relays that can be configured to control the following; Heat Stage 3 Select this option when the Thermostat is required to control a 3-stage conventional heating system. Connect the third stage (or W3) contact to this accessory relay.
